TEMPLET- Specification of Letters Patent.

Patented Aug. 21, 1906.

Application filed September 19, 1905. Serial No. 279.166.

T 0 all whom, it may concern:.

Be it known that 1, JOHN K. GRAHAM, a citizen of the United States, residing in Wilmington, Delaware, have invented certain Improvements in Templets, of which the following is a specification.

My invention relates to certain improvements in templets for marking out centers on bridge, ship, or structure metal-work, as set forth in the application for atent filed by John D. Cummings, Serial 0. 232,033, November 9, 1904, allowed May 29, 1905.

The object of my invention is to provide a templet for use in marking and punchingthe centers of angle-beams, channel-bars, and other an ular shapes. This object I attain in the fol owing manner, reference bein had to the accompanying drawings, in whic Figure 1 is a perspective view of my improved templet shaped to be used in marking out the centers on angle-bars. Fig. 2 is a view showing my improved templet shaped to be used in marking out centers on channel bars or beams. Fig. 3 is a view illustrating the method of applying the templet to a bar, and Fig. 4 is a view illustrating a templet applied to the bar and a center punch in position.

Referrin in the first instance to Fig. 1, A is the temp iet, having two members a, a, one arran ed at an angle to the other, preferably little Iess than a right angle, as shown at Fig. 3, so that when the templet is appliedto the beam it can be forced into position, as shown in Fig. 4, and will fit tightly a ainst the two surfaces 6 b of the bar or beam The templet has holes 0 punched at intervals for the reception of the guiding-sleeve e of the punch E. This guiding-sleeve fits snugly in the hole a and when in place, as shown in Fig. 4, acts as a support and guide for the plunger of the punch E, which has a small projection e to form the center punch-hole in the bar or beam B. In making the templet A, I use cardboard or binders board of sufficient thickness that will give the templet rigidity. I then score it on the line :10, so as to out partly through the cardboard, and then bend it as shown in Fig. 1, after which, while the templet is held at the angle desired, staples I are secured to both parts a a of the templet, as

illustrated in Figs. 1 and 3, the ends i of the staples which extend through the cardboard being clenched on the under side. When the staples are secured, the templet is of sufiicient rigidity to withstand the rough usage to which a templet in a bridge or structural iron shop is subjected. As before remarked, the templet is preferably shaped to a little less than a right angle, so that it can be forced onto the right-angle beam or bar, as indicated in Figs. 3 and 4, but it may be made exactly at right angles in some instances, if desired.

In Fig. 2 I have shown a templet for use in marking out centers on channel-bars. In this construction the templet is made with center section A and side sections a a each sponding to the holes to be punched in the channel-beam. If other angular shapes are to be punched, the templet can be made accordingly.

I claim as my invention- 1. A templet for marking out centers in angle-work, consisting of a sheet of cardboard cut partially through at the bendingline and bent away from the cut so as to open the same, to form two sections, one at an angle to the other, with a series of staples reinforcing the said angle-joint, the ends of the staples being embedded in the material so as to form a smooth inner surface in order that the templet can be placed in close contact with the angle shape to which it is applied, substantially as described.

2. A templet for marking out centers in angle shapes, consisting of a sheet of cardboard cut partially through and bent away from the cut so as to open the same, to form two sections, said sections being bent at a little less than the angle of the bar or shape to which it is to be applied, so that on pressing the templet in position it will fit snugly upon the surface of the angle bar or shape, substantially as described.

3. A templet for markin centers in channel-bars, consisting of a body portion having two side sections cut partially through at the lines of junction with said body portion and bent away from the cuts so as to open the same, with a series of reinforcing-staples con necting the body portion with each of the side sections, the ends of the sta les being 5 embedded inthe material so that tlle templet will snugly fit the channel, substantially as described In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
